Good, very easy. Three rounds if I remember correctly. One initial phone screen another with a member on the team and then a super day where you present your analysis.

Three rounds of interviews, two over phone and a 3 hour long interview in person. The first two interviews consisted of a 30-minute screening call and a chat with a senior consultant at FI, while the 3-hour interview consisted of 3 parts; a case review, a technical interview, and a team-fit interview, each an hour long.
